Description
LCA220 is a common input 1- Form 2A solid state relay
which has two independent optically couple MOSFETs
controlled by a common input signal. The efficient MOS-
FET switches and photovoltaic die use Clare’s patented
OptoMOS architecture to provide 3750 V_RMS of input to
output isolation. The optically coupled input is controlled
by highly efficient GaAIAs infrared LEDs. Common input
OptoMOS relays can replace standard dual pole relays in
a variety of applications. The common input relay elimi-
nates the need to make an external circuit connection
when both poles are controlled by a common signal.
